ACTIVE/STANDBY PW REDUNDANCY FOR EPIPES
Various exemplary embodiments relate to a method performed by a backbone network for performing switchover of plurality of pseudo-wires (PWs) connecting a customer edge device to a primary backbone edge bridge (BEB), the method including: designating one of the plurality of PWs as a control PW; associating the remaining PWs with the control PW; associating a virtual backbone MAC (B-MAC) address with the control PW; and advertising, by the primary BEB, the virtual B-MAC address to the backbone network.
1 . A method performed by a backbone network for performing switchover of plurality of pseudo-wires (PWs) connecting a customer edge device to a primary backbone edge bridge (BEB), the method comprising:
designating one of the plurality of PWs as a control PW;
associating the remaining PWs with the control PW;
associating a virtual backbone MAC (B-MAC) address with the control PW; and
advertising, by the primary BEB, the virtual B-MAC address to the backbone network.
2 . The method of claim 1 , further comprising:
initiating a switch over by a customer edge device of the plurality of PWs from the primary BEB to a plurality of redundant PWs connected to the redundant BEB; and
advertising by the redundant BEB the virtual B-MAC address to the backbone network.
3 . The method of claim 2 , further comprising:
designating one of the plurality of redundant PWs as the control PW.
4 . The method of claim 1 , wherein the virtual B-MAC address is associated with the primary BEB and the secondary BEB.
5 . The method of claim 1 , wherein the virtual B-MAC address is advertised using the shortest path bridging MAC (SPBM) protocol.
6 . The method of claim 1 , wherein the plurality of PWs are all on a service distribution point (SDP).
7 . The method of claim 6 , wherein the plurality of PWs include all of the PWs on the service distribution point (SDP).
8 . A network device for performing switchover of plurality of pseudo-wires (PWs) connecting a customer edge device to a primary backbone edge bridge (BEB), the network device comprising:
a network interface; and
a processor configured to:
designate one of the plurality of PWs as a control PW;
associate the remaining PWs with the control PW;
associate a virtual backbone MAC (B-MAC) address with the control PW; and
advertise the virtual B-MAC address to the backbone network.
9 . The network device of claim 8 , wherein the virtual B-MAC address is associated with the primary BEB and the secondary BEB.
10 . The network device of claim 8 , wherein the virtual B-MAC address is advertised using the shortest path bridging MAC (SPBM) protocol.
11 . The network device of claim 8 , wherein the plurality of PWs are all on a service distribution point (SDP).
12 . The network device of claim 8 , wherein the plurality of PWs include all of the PWs on the service distribution point (SDP).
13 . A non-transitory machine-readable storage medium encoded with instructions for execution by a backbone network for performing switchover of plurality of pseudo-wires (PWs) connecting a customer edge device to a primary backbone edge bridge (BEB), the non-transitory machine-readable storage medium comprising:
instructions for designating one of the plurality of PWs as a control PW;
instructions for associating the remaining PWs with the control PW;
instructions for associating a virtual backbone MAC (B-MAC) address with the control PW; and
instructions for advertising, by the primary BEB, the virtual B-MAC address to the backbone network.
14 . The non-transitory machine-readable storage medium of claim 13 , further comprising:
instructions for initiating a switch over by a customer edge device of the plurality of PWs from the primary BEB to a plurality of redundant PWs connected to the redundant BEB; and
instructions for advertising by the redundant BEB the virtual B-MAC address to the backbone network.
15 . The non-transitory machine-readable storage medium of claim 14 , further comprising:
instructions for designating one of the plurality of redundant PWs as the control PW.
16 . The non-transitory machine-readable storage medium of claim 13 , wherein the virtual B-MAC address is associated with the primary BEB and the secondary BEB.
17 . The non-transitory machine-readable storage medium of claim 13 , wherein the virtual B-MAC address is advertised using the shortest path bridging MAC (SPBM) protocol.
18 . The non-transitory machine-readable storage medium of claim 13 , wherein the plurality of PWs are all on a service distribution point (SDP).
19 . The non-transitory machine-readable storage medium of claim 13 , wherein the plurality of PWs include all of the PWs on the service distribution point (SDP).
